In the last 24 hours, the seismic records of the surveillance system at Popocatépetl volcano registered 5 low-intensity exhalations, and two explosions, the first one yesterday at 12:27 h and the second one tonight at 00:49 h; this last one expelled incandescent fragments up to 2 km from the crater.
Additionally, during this period several episodes of harmonic tremor were registered, which in total added up to 362 minutes. This activity is related to the process of construction of a lava dome presently inside the crater.
Yesterday, with the aid of the Federal Police, an over flight was made, during which it the presence of a 300 m in diameter dome was verified, which has filled the inner crater almost to the level of the main crater´s floor . The presence of this dome implies the possibility of further explosions in the next few days, of similar or even slightly larger magnitude than tonight´s, which destroy it.
Since this morning and up to the time of this report the volcano has been visible, with a slight emission of steam and gases which the winds disperse towards the east-northeast .
CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments .
This type of activity is included within the scenarios Volcanic Traffic Light Yellow Phase 2.
